Introduction
The FX-850 and FX-1050 printers combine all the well-known features of previous Epson ® 9-pin printers with many features normally exclusive to costly 24-pin printers.
Features
In addition to the high-quality printing and ease of operation you’ve come to expect from Epson printers, the FX-850 and FX-1050 offer the following:
An advanced paper handling system that lets you use single sheets of paper without removing the continuous paper. This system allows you to use continuous paper even while the optional cut sheet feeder is attached.
A new short tear-off feature that saves paper. After you tear off the last sheet printed on continuous paper, the printer reverses the paper so that you can use all of the next sheet.
A micro-adjustment feature that allows you to feed the paper forward or backward to finely adjust the loading and short tear-off positions.
An improved control panel design that allows direct selection of character fonts and pitch, as well as a choice of draft or near letter quality (NLQ) printing.
Draft mode with fast printing of up to 264 characters per second at
12 cpi.
The ability to handle a wide range of paper types, including envelopes.
Double-high and double-wide printing for headings and special emphasis.
Introduction 1

Paper Handling
2-1
Using Single Sheets
Your printer can handle a wide range of paper sizes up to a maximum width of 10.1 inches on the FX-850 or 14.4 inches on the FX-1050.
Always make sure that your printing is confined to the size of paper you are using. Never print on the platen (black roller).
If you do most of your printing on single sheets, you may find it more convenient to install the optional cut sheet feeder. This option automatically inserts a new sheet whenever required and can hold up to
150 pages or 25 envelopes. For more details, see Chapter 7.
To load a single sheet of paper follow these steps:
Note: If you already have continuous paper loaded, follow the instructions on page 2-10 for switching between continuous paper and single sheets.
1.
Turn on the printer.
2.
Push the paper release lever back to the single sheet position.
2-2 Paper Handling
3.
Stand the paper guide in an upright position and align the left edge guide with the arrow on the paper guide. (You may want to change this position later, depending on the margin settings of your application program.)
4.
Adjust the right edge guide to fit the size of the paper.
5.
Slide the paper down between the edge guides until it meets resistance. At this point, the PAPER OUT light turns off.
6.
Press the LOAD/EJECT button to automatically feed the paper to the loading position.
WARNING: Never advance the paper using the platen knob while the printer is turned on.
7.
Press the ON LINE button so that the ON LINE indicator lights up.
Paper Handling 2-3
If the platen (black roller) turns but the sheet does not load, remove the sheet completely from the printer. Then make sure the paper release lever is pushed back. Press the paper a bit more firmly into place and try again.
To eject the paper, press the ON LINE button to take the printer off line, and press the LOAD/EJECT button.
Reloading during printing
When you print a document more than one page long using single sheet paper, the printer stops printing when it reaches the bottom of the paper and ejects the page. When this happens, either the ON LINE light goes off automatically or it may remain on, depending on your application software. If the ON LINE light remains on, the first thing you should do is press the ON LINE button to take the printer off line. Once the ON LINE light is off, remove the sheet that has just been printed and load a new sheet as before. Press ON LINE to start printing the next page.
Using Continuous Paper
The tractor built into the FX is remarkably easy to load and operate. Its low-profile design takes up little space and can handle a wide variety of paper widths.
To load continuous paper, follow these steps:
1. Turn off the printer.
2.
Pull the paper release lever forward to the continuous paper position.
2-4 Paper Handling
3. Release the sprocket lock levers by pulling each lever forward.
4.
Slide the left sprocket unit all the way to the left and lock it in place.
Paper Handling
2-5
5. Next, slide the right sprocket unit to match roughly the width of your paper. (Do not lock it.)
6. Slide the paper support to a point midway between the sprocket units.
7. Open both sprocket covers.
2-6 Paper Handling
8. Fit the first four holes in the paper over the pins of the sprocket units as shown below. Then close the sprocket covers.
9. Slide the right sprocket unit to a position where the paper is straight and has no wrinkles, and then lock it in place.
10. Reattach the paper guide as shown below.
Paper Handling 2-7
Caution: When using continuous paper, always make sure that the edge guides are pushed together.
11. Close the printer cover and turn on the printer.
12. Press the LOAD/EJECT button to feed the paper to the loading position. The printer remembers this position and advances each page to the same position.
13. Press the ON LINE button to put the printer on line so that it can accept data.
If you find that your word processing or other application program prints too high or too low on the page or is printing on the perforations, check the loading position. If you need to adjust this position, you can use the micro-adjustment feature. This feature gives you precise control over the position of your paper by allowing you to feed the paper forward or backward in 2/216-inch increments. For more information, see the section on micro-adjustment later in this chapter.
When using continuous paper, you can also choose the short tear-off feature to give you added paper handling capabilities. This feature automatically feeds the paper forward so that you can tear it off at its perforation. The printer then reverses the paper feed so you can resume printing at the loading position. Short tear-off makes it easier to detach printed pages and saves the blank pages that are usually lost between printing jobs. See the section on short tear-off later in this chapter for details.
WARNING: If you need to adjust the loading position, always use the micro-adjustment feature. Never advance the paper using the platen knob while the printer is turned on.
2-8 Paper Handling
Positioning your continuous paper supply
Three common ways of positioning your printer and continuous paper supply are shown below.
It’s important to keep your paper supply aligned with the tractor so that the paper feeds smoothly into the printer.
Paper Handling 2 - 9
Switching Between Continuous and Single Sheets
Even with continuous paper loaded in the printer, you can easily switch to single sheet printing without removing the continuous paper from the tractor. To switch from continuous paper to single sheets, follow the steps below.
1.
Open the printer cover and press the ON LINE button to take the printer off line.
2.
Remove your printed document. If you are not using the short tearoff function, press the FORM FEED button to advance your document to a point where it can be removed.
Note: To avoid feeding your continuous paper backward more than is necessary, always make sure that you tear off the printed document before removing paper with the LOAD/EJECT button.
2-10 Paper Handling
3.
Press the LOAD/EJECT button to feed the continuous paper backward out of the printer and into a standby position. The paper is still attached to the tractor, but is no longer in the paper path. The
PAPER OUT light comes on when the paper is completely out of the paper path.
Note: Pressing the LOAD/EJECT button once may not feed the paper back enough to reach a standby position. If the PAPER OUT light does not come on, press the LDAD/EJECT button again. With normal continuous paper, you can press the LOAD/EJECT button up to three times. (With continuous paper narrower than six inches, you can press the LOAD/EJECT button only once.)
4.
Push the paper release lever back to the single sheet position.
Paper Handling 2-11
5.
Stand the paper guide upright, and adjust the edge guides to roughly match the width of your paper.
6.
Close the printer cover. Next, slide the paper between the edge guides until it meets resistance. At this point, the PAPER OUT light turns off.
7.
Press the LOAD/EJECT button to automatically feed the page to the loading position.
2-12 Paper Handling
8.
Press the ON LINE button to put the printer on line.
Switching back to continuous paper
To switch back to printing with continuous paper, first eject the single sheet of paper and take the printer off line.
1.
Open the printer cover. Lower the paper guide onto the back of the printer.
2. Pull the paper release lever forward to the continuous paper position.
3.
Press the LOAD/EJECT button to feed the paper to the loading position.
4.
Press the ON LINE button to put the printer on line.
Paper Handling 2-13
Adjusting the Loading Position
The loading position is the position of the paper when it has been automatically loaded by the printer. This position is important because it determines where the printing begins on the page. If the printing is too high or too low on the page, you need to change the loading position using the micro-adjustment feature described in the next section.
Until the loading position is reset, the printer remembers the position and uses it as a reference point for feeding the paper.
WARNING: If you need to adjust the loading position, always use the micro-adjustment feature. Never use the platen knob for paper feeding except in case of a paper feeding problem.
Once you have used micro-adjustment to change the loading position of continuous paper, the printer remembers that position even after it is turned off. However, when you use micro-adjustment to change the loading position of single sheet paper, the printer does not remember this position after the power is turned off. When the power is turned back on, the loading position returns to its factory setting.
Using Micro-Adjustment
The micro-adjustment feature moves the paper 2/216th of an inch at a time to make fine adjustments to the loading or short tear-off positions.
Micro-adjustment only works immediately after you load paper or use the short tear-off function. You can use micro-adjustment only when the printer is on line and the ON LINE indicator light is flashing.
After you adjust the tear-off position or after you adjust the loading position for continuous paper, the printer remembers that position even after it is turned off, reset, or initialized. However, when you adjust the loading position for single-sheet paper, the printer does not remember the new position after the power is tuned off.
2-14 Paper Handling
This section describes using micro-adjustment to change the loading position, but you can adjust the short tear-off position the same way. See the next section on using short tear-off for more information.
To perform micro-adjustment of the loading position, first load your paper, and then press the ON LINE button to put the printer on line. The
ON LINE indicator light starts to flash. While this light is flashing, you can use the FORM FEED and LINE FEED buttons for micro-adjustment.
Press the FORM FEED button to feed the paper forward or the LINE FEED button to feed the paper backward.
Each time you press the button, the paper moves 2/216 of an inch. If you hold the button down, the paper moves continuously in 2/216-inch increments.
When the paper reaches the factory-set loading position, the printer beeps and micro-adjustment feeding pauses for a moment before continuing. You can use this factory setting as a reference point when adjusting the printer’s loading position. When the paper reaches either the minimum or maximum top margin, the printer beeps and the paper stops moving.
Using Short Tear-Off
When you are finished printing, the short tear-off feature automatically feeds the perforation of the continuous paper to the tear-off edge of the printer cover so that you can tear off the last sheet. When you resume printing, the printer reverses the paper back to the loading position so that you can use all of the next sheet.
WARNING: Never use short tear-off with labels.
To use short tear-off, first turn off the printer and turn DIP switch 1-5 off. (See the section on setting DIP switches in Chapter 3.) Then load continuous paper as usual, but leave the rear section of the printer cover open so that you can use the cover as a tear-off edge.
Paper Handling 2-15
The short tear-off function operates as follows:
1. The perforation at the end of the last printed page feeds to the tear-off edge of the printer cover.
2. Tear off the page using the printer cover’s tear-off edge.
3. If you need to adjust the position of the perforation to meet the tearoff edge, use micro-adjustment. This feature adjusts your tear-off position only when you use it immediately after short tear-off. First, make sure that the printer is on line and the ON LINE indicator light is flashing. Then, adjust the position in 2/216th-of-an-inch increments by pressing the FORM FEED button to feed the paper forward or the
LINE FEED button to feed it backward.
After micro-adjustment, the new tear-off position is reset and remains valid even after the printer is turned off, reset, or initialized.
4. When you resume printing after tearing off the sheet, the paper automatically feeds backward to the loading position before printing begins.
2-16 Paper Handling
You can leave the short tear-off feature turned on (DIP switch 1-5 off) even when you are using single sheets. When you move the paper release lever to the single sheet position, short tear-off is disabled.
Printing on Special Paper
In addition to using single sheets and continuous paper, your printer can also print on a wide variety of paper types, including multi-part forms and labels. You can even feed envelopes, either manually or with the optional cut sheet feeder. Before printing on these special types of paper, however, you need to adjust the paper thickness setting.
The paper thickness lever
To accommodate various thicknesses of paper, the FX printer is equipped with a paper thickness lever that can be set to eight positions. These positions are identified by a scale on the printer frame next to the lever.
Before changing the paper thickness setting, first make sure the power is off and then remove the printer cover.
WARNING: If you’ve been using the printer just before opening the printer cover, be careful not to touch the print head because it may be hot.
Select the paper thickness you want according to the figure below. For normal use, the lever should always be set to position 2 on the scale.
Paper Handling 2-17
For printing on special types of paper, see the table below. It gives you general guidelines for selecting the right paper thickness lever position to match your paper.
Paper Type

Always return the lever to position 2 when you go back to printing on ordinary paper. Continuous printing with the lever set at a position higher than 2 can shorten the life of the print head.
77
WARNING: Printing past the edge of envelopes, multi-part forms, labels, or thick paper can damage the print head.
When you print on anything thicker than normal paper, such as envelopes or multi-part forms, be absolutely sure that your printing stays within the printable area of the paper. See page 2-20 and Appendix A for more about the printable area of the paper.
Multi-part forms
Your printer can also use continuous multi-part forms. These multiple forms should have no more than four parts including the original.
Note: Multi-part forms should not be used with the single sheet feeding system or the optional cut sheet feeder.
Paper Handling
2-18
You load continuous multi-part paper the same way that you load continuous paper. See the section on loading continuous paper in this chapter for details. The only difference is that you need to adjust the paper thickness lever to suit the thickness of your paper before loading.
See the table above for the correct paper thickness setting.
Labels
If you need to print labels, always choose the type mounted on a continuous base sheet provided with sprocket holes for use with the tractor. If you attempt to print labels using the single-sheet feeding system, labels on a shiny base sheet almost always slip a little.
You load labels the same way that you load continuous paper. See the section on loading continuous paper in this chapter for details. The only difference is that you need to adjust the paper thickness lever to match the thickness of your labels. See the table above for the correct paper thickness setting.
To remove labels, tear off at a perforation behind the push tractor. Then take the printer off line and use the FORM FEED button to eject the labels.
WARNING: Never feed the labels backward through the printer. Labels can easily come off the backing and jam the printer. Therefore, never use the LOAD/EJECT button to eject labels or to feed labels backward to the standby position.
Also, never use the short tear-off feature with labels. If a label does become stuck in the printer mechanism, take the printer to a qualified service person. Since labels are especially sensitive to temperature and humidity, always use them under normal operating conditions.
Envelopes
You can print on a variety of envelopes, including air mail, plain, or bond. To feed envelopes individually, use the single sheet loading feature.
First, set the paper thickness lever as indicated in the table above. Then, follow the single sheet loading instructions at the beginning of this chapter.
Paper Handling 2-19
You can also feed envelopes with the optional cut sheet feeder. See the section on the cut sheet feeder in Chapter 7. Before loading envelopes into the cut sheet feeder, you need to adjust the paper thickness lever. See the table showing envelope types and recommended lever positions on page 2-18.
2-20
WARNING: When printing on envelopes, be sure that your application program settings keep the printing entirely within the printable area of the envelopes as shown below.

International character sets
Default character set
When DIP switch 1-1 is on, the user-defined character set is the default.
User-defined characters are maintained in printer memory even when the power is turned off, so the user-defined character set can be selected simply by setting this switch to on. However, when this switch is on, new user-defined characters cannot be defined. See Chapter 4 for more information on user-defined characters. This switch is effective only in the Epson ESC/P mode.
Zero character
When DIP switch 1-2 is on, the printer prints slashed zeroes (0). When the DIP switch is off, the printer prints open zeroes (0). This is useful for clearly distinguishing between uppercase 0 and zero when printing such items as program lists.
Character table
When DIP switch 1-3 is on, the Epson Extended Graphics character table is selected. When it is off, the italics character table is selected. The Epson
Extended Graphics character table contains international accented characters, Greek characters, and character graphics for printing lines, comers, and shaded areas. If you have an IBM
®
computer or an IBM compatible, select the Epson Extended Graphics table when you wish to print the character graphics as they are displayed on the screen. Since the character table setting affects only half of the character table, you can
Using the Printer 3-7
still print text if you have selected the Extended Graphics set. Also, you can still print italics if you use the proper software command. If your printer is in IBM emulation mode (DIP switch 1-4 on), the graphics characters are available no matter which character table you select.
The printouts below show which characters are printed in each table.

Epson Extended Graphics
Note: You may need to use the ESC 6 command to print some of the
Extended Graphics characters. See Appendix B.
Printer mode
When DIP switch 1-4 is on, the printer operates in the IBM emulation mode. When it is off, the printer operates in the Epson ESC/P mode. In the IBM emulation mode, DIP switch 1-3 controls the automatic carriage return. When switch 1-3 is off, a carriage return is added to each line feed. The functions of DIP switches 1-6, 1-7, and 1-8 are also different when using the printer in the IBM emulation mode. For details, see the section on international character sets on the next page.
Short tear-off mode
When DIP switch 1-5 is off, the short tear-off mode is on. This feature advances the paper so you can tear off the paper, and then reverses the paper so you can use all of the next sheet. See the section on using short tear-off in Chapter 2.
3-8 Using the Printer
International character set
Selecting an international character set provides you with the characters used in other languages. To obtain the desired international character set, set switches 1-6, 1-7, and 1-8 according to the DIP switch table on page
3-7. The following table shows the characters that differ in each international character set.

Also, in IBM emulation mode (DIP switch 1-4 on), a character set containing international characters (CG character table 2) is selected whenever any one of DIP switches 1-6, 1-7, or 1-8 is set to off. If all three switches are on, CG character table 1 is selected. See Appendix B.
Page length
When DIP switch 2-1 is on, the page length is set to 12 inches. When it is off, the page length is 11 inches. Other page lengths can be set with the ESC C and ESC CO commands. See the Command Summary in
Chapter 8.
Using the Printer 3-9
Cut sheet feeder mode
When DIP switch 2-2 is on, you can use your printer’s optional cut sheet feeder. See Chapter 7 for more information on using a cut sheet feeder with your printer.
Skip over perforation
When DIP switch 2-3 is on, a one-inch margin is provided between the last line printed on one page and the first line printed on the next page.
When using continuous paper, this feature causes the printer to stop printing, skip over the perforation, and then resume printing. If you adjust your loading position correctly, you can get half of the margin at the bottom of one page and half at the top of the next page. See the section on adjusting the loading position later in this chapter.
Note: Most application programs take care of the top and bottom margins. Only use skip over perforation if your program does not provide these margins.
Automatic line feed
When DIP switch 2-4 is on, a carriage return code (CR) causes an automatic line feed. When it is off, line feeds occur only when the printer receives line feed codes (LF). Since some computers and application programs automatically add line feeds to carriage returns, the setting you use depends on your computer and application program.
Selecting Typestyles
Your printer can produce a wide range of typestyles by combining different character fonts, pitches, widths, and other enhancements. These features can be selected by using the SelecType feature on your control panel or by using software commands. This section describes only the features controlled by SelecType. To use software commands, see the section on computer-printer communication in Chapter 4 and the
Command Summary in Chapter 8.
3-10 Using the Printer
Using SelecType
You can use the SelecType control panel to choose fonts, pitches, and condensed printing. The settings you select using the SelecType panel remain valid even after the printer is turned off, reset, or initialized.
However, commands from your software application program temporarily override the SelecType settings.
Character fonts
The FX-850 and FX-1050 have three built-in character fonts:
ROMAN
!“##$%&-( )*+,./0123456789:;<=>?6’ABCDEFGHIJK
LMNCPQRSTUWXYZ[\]^-‘

Using the Printer 3-11
The draft mode uses fewer dots per character for high-speed printing.
This makes draft ideal for rough drafts and editing work.
Roman and Sans Serif are near letter quality (NLQ) fonts. Near letter quality takes a little longer to print but produces nicely formed characters suitable for most documentation requirements.
Characters per inch
For each of the three built-in fonts, you can choose a character size of 10 or 12 characters per inch (cpi), or proportional spacing.
The following printout compares the different types of spacing.
This is Roman printing in 10 cpi.
This is Roman printing in 12 cpi.
This is Roman printing in proportional.
In the 10 and 12 cpi modes, each character is given the same amount of space. However, in the proportional mode, spacing varies from character to character. Therefore, a narrow letter like the lowercase i receives less space than a wide letter like the uppercase W.
Condensed mode
In addition to the two pitches and proportional spacing, you can use the condensed mode to change the character size. In the condensed mode, characters are approximately 60% of the width of normal characters.
Condensed printing is very useful for spreadsheets and other applications where you need to print the maximum amount of information on a page.
Both 10 and 12 cpi can be condensed, but proportional spacing cannot.
The printout below compares normal 10 cpi with condensed 10 cpi.
T h i s i s 1 0 c p i R o m a n p r i n t i n g .
This is condensed 10 cpi Roman printing.
3-12 Using the Printer
Note: Proportional spacing and condensed mode cannot be combined.
If you select both, only proportional spacing works.
If SelecType does not work
Some application programs are designed to control all typestyle functions. These programs cancel all previous typestyle settings by sending certain software commands before printing. Because these commands cancel SelecType settings, you should use the program’s print options function instead of SelecType to select your typestyles.
Therefore, if SelecType does not work with a particular application program, consult the software manual for information on selecting typestyles. Also, see the section on using the FX with application software in Chapter 4.
Enhancing Your Printing
SelecType controls the printing style of a whole document. Software commands, on the other hand, can change anything from a single character to the entire document. By using software commands, you can obtain many different printing effects with the FX printer, from arranging the text on the page to giving extra emphasis to particular words and phrases. This section shows you the features you may want to select with your software. Once you have read about the features, you can find their commands in the Command Summary in Chapter 8. Also, see the section on computer-printer communication in Chapter 4 for more information on sending commands to the printer.
Character size
Besides 10 and 12 cpi, condensed printing, and proportional spacing, software commands also offer two other options: double-wide and double-high printing.
Using the Printer 3-13
The double-wide mode doubles the width of any size characters. This mode is useful for such purposes as emphasizing headings in reports and making displays, but is usually not suitable for large amounts of text.
T h i s i s d o u b l e - w i d e -
Another mode for headings and other special uses is double-high:
This is double-high.
Because of its height, you must leave a blank line above a line of double- high printing. Otherwise, the double-high letters will overlap the letters on the previous line.
Double-wide and double-high can be combined to obtain even more impressive printing results:
D o u b l e - h i g h d o u b l e - w i d e
Widening or narrowing the characters also widens or narrows the spaces between words and letters. Because word processors usually create a left margin by printing spaces, you may need to change the number of characters on a line to keep the margins correct if you change widths.
For example, a left margin of 10 characters at space margin using double-wide characters.
10 cpi is the same as a five-
Emphasized and double-strike printing
Emphasized and double-strike printing give your documents added emphasis. In emphasized mode, the FX prints each character twice as the print head moves across the paper, with the second printed slightly to the right of the first. This process produces darker, more fully formed characters.
3-14
Using the Printer
In double-strike mode, the printer prints each character twice, the second time slightly below the first, making the text bolder. For even greater boldness, you can combine emphasized and double-strike. (Double-strike cannot be combined with NLQ mode, however.)
Italic printing
You can use italic characters for special emphasis or as an alternative typeface. ESC 4 turns on the italic mode even if the current DIP switch setting is set to the Epson Extended Graphics character table.
This sentence is in italics.
Underlining
The underline mode automatically underlines any piece of text. It underlines spaces, subscripts, and superscripts. (The printer does not, however, underline horizontal tabs.)
Superscripts and subscripts
Superscripts and subscripts can be used for printing footnote numbers and mathematical formulas. The example below combines underlining, superscripts, and subscripts in a mathematical formula.
a v e r a g e = ( a 1 + . . . . . . . . . . . . . . . . + a n ) n
Selecting typestyles with Master Select
Your printer has a special command called Master Select that allows you to choose many possible combinations of nine different modes. To send
Master Select codes to the printer, you must first choose the mode combination you want. The modes you can choose from are 10 cpi, 12 cpi, proportional, condensed, emphasized, double-strike, double-wide, italics, and underline.
Using the Printer 3-15
The format of the Master Select code is shown below:
ASCII:
Decimal:
ESC 1 n
27 33 n
Hexadecimal: 1B 21 n
To send the Master Select codes to your printer in a decimal format, for example, you send the codes 27, 33, and then whatever value you choose for the variable n.
The variable n is a number that identifies the typestyle or combination of typestyles. To find the value of n, look at the Master Select table below and add up either the decimal or hexadecimal numbers for the features you want.
Master Select Table
For example, if you want to print a title using double-wide 12 cpi characters in double-strike mode, you would add these three decimal numbers together to calculate the value of n:
12 cpi
Double-strike
Double-wide
1
16
32 n =
49
3-16 Using the Printer
After calculating the value of n, you use the Master Select command to send the value to the printer. To send the Master Select command for double-wide, 12 cpi, and double-strike, you would use the decimal codes
27, 33, and 49.
ASCII:
Decimal:
Hexadecimal:
ESC ! 1
27 33 49
1B 21 31
Consider these things when you use the Master Select command: l l
Master Select cancels any of the listed features that you do not set.
For example, if you have already set 12 cpi, and you try to use
Master Select to set emphasized double-strike only, the character width is reset to 10 cpi.
Proportional overrides 10 cpi, 12 cpi, and condensed.

Double-strike cannot be combined with NLQ mode.
Print quality and font are not part of Master Select and must be set separately, using either SelecType or the ESC x and ESC k commands.
The method you use to send the Master Select codes to the printer is determined by your application software. For more information on sending commands to your printer, see the Computer-Printer
Communications section in Chapter 4 and the Command Summary in Chapter 8.

Using the FX with Application Programs
Now that you’ve set up and tested the printer, you need to start using it with your application programs.
Most application programs let you specify the type of printer you’re using so that the program can take full advantage of the printer’s features. Many programs provide an installation or setup procedure that presents a list of printers to choose from. If your application program has a printer selection menu, use the instructions below.
Using printer selection menus
If your software has a printer selection menu, simply choose FX-850 or
FX-1050. If the menu does not list either of these printers, choose the following. They are listed in order of preference.

Note: If your application program does not list the FX-850 or FX-1050, you may want to contact the
software manufacturer to see if an update is available.
4-2 Using Software and Graphics
A quick test
After setting up your application program, print a sample document to make sure the program and the FX are communicating properly. If the document doesn’t print correctly, recheck the program’s printer selection and installation procedure. If you’re still having trouble printing, consult the troubleshooting section in Chapter 6.
Using word processors
Word processors usually let you use a fixed set of printer features by placing markers around the text to be altered. When the document is printed, the markers are recognized and translated into suitable commands for your printer. On your screen some programs show the markers; others display the text as it will appear-for example, in bold or italics. This method is normally restricted to features that can be found on almost all printers, such as bold and underlining.
Some word processing programs also let you insert printer commands in your text. These commands may or may not be visible on your screen.
This method has the advantage of allowing you to use any printer command, not just a limited set. To make use of it, however, you need to understand how to use your printer’s commands. Check the manual for your word processor to see if you can place printer commands in your text, and then see the section in this chapter on computer-printer communications.
Using spreadsheets
Although spreadsheets seldom use as many printing styles as word processors, they do have some very specific requirements.
If your spreadsheet program provides a list of printers, use the list on page 4-2 to find the proper selection. If your spreadsheet doesn’t printer setup routine, read the program’s manual carefully for information on printing.

A major concern for printing spreadsheets is the width of the printer. The

panel. The table below shows you many characters you can fit on a line using these options. If your spreadsheet asks the number of columns your printer can print, decide which mode you will use and supply the appropriate number from this table.
Unlike word processors, spreadsheet programs usually don’t let you change printer commands within a spreadsheet. Instead, one style or mode of printing is used for the whole spreadsheet. With the FX, there are two main ways of sending commands to control the printing of a spreadsheet. The first method is to choose condensed from the SelecType control panel.
For the second method, look in the manual for your spreadsheet to find out how to send printer commands. Then look in the Command
Summary in Chapter 8 to find the proper codes to send.
For example, your spreadsheet might use a “setup string” to send printer commands. To prepare a setup string for 12 cpi condensed, you would look up the proper command in the Command Summary. The command for
12 cpi is ESC M, and the command for condensed is SI. Because most spreadsheets use the decimal equivalent for the commands, (also given in the Command Summary), a setup string for 12 cpi condensed might look like this:
/027/077/015
The number

027 is for the escape code,
077 is for M, and
015 is for SI

Using graphics software
The FX is capable of producing finely detailed graphic images. Although the section on graphics later in this chapter gives specific information on the graphics commands, the easiest way to take advantage of the FX’s capabilities is with one of the many graphics programs available.
When buying graphics software, always make sure the program has an option to print on an FX printer. Any program with an option for an FX printer should give excellent results, using different dot densities to produce a realistic scale of grays.
Most graphics programs have a printer selection procedure, in which case you should check the lists on page
4-2 to find the proper selection.
Computer-Printer Communication
Your computer communicates with your printer using a standardized set of numbered codes it is translated into called ASCII codes (American Standard Code for
Information Interchange). When you press the letter A on the keyboard, the ASCII code for A, transmitted to a peripheral device such as your computer screen or your printer, and then converted back into the letter A.
There are ASCII codes for all the letters in the alphabet, both uppercase and lowercase letters, and for the numbers 0 through 9. The ASCII set of codes also includes most punctuation marks and some codes that control printer functions.
In the Command Summary in Chapter 8, each code is expressed three different ways: as an ASCII character, as a decimal number, and as a hexadecimal (base
16) number. For example, the uppercase letter A is represented as the ASCII character A, the decimal number 65, and the hexadecimal number 41. The numbering system you use depends on your software and your preferences.
All letters, numbers, and punctuation marks are assigned decimal numbers from than
32
32 through
255.
ASCII codes with decimal values of less are called control codes, because they control the operation of
Using Software and Graphics 4-5
your printer and other peripherals. These ASCII characters do not usually have corresponding keys on the keyboard and cannot be printed as characters by your printer.
Escape sequences
Although there are more than 30 control codes available to control the operation of your printer, many more codes are required to run today’s sophisticated printers. Therefore, ASCII codes are grouped in sequences to represent certain functions. These code sequences use the ASCII codes with decimal values of 32 through 255, normally reserved for characters and punctuation, to control printer functions. This is done by first sending a standard code to tell the printer that the codes that follow are to be used as control codes, not as characters or punctuation.
The standard code that is sent at the beginning of one of these code sequences is the Escape code, decimal value 27. Any sequence of codes starting with the Escape code is called an Escape sequence. You will probably see Escape written in different ways-such as ESC, E SC , and
ESCape-in various manuals. In this manual it is in the form of ESC when used within a command.
Printer commands
In order for the printer to recognize the instructions it receives, ASCII codes must be sent in a specific format, called a command. An Escape sequence is a command, as is any ASCII code or sequence of codes that instructs the printer to carry out a particular function. Your software continually sends commands to your printer and your computer screen.
These commands instruct the printer to perform such actions as print in a particular typeface, feed the paper a certain amount after printing each line, and start printing on a particular spot on the page.
Some software programs let you send these commands yourself. This is a powerful feature because it allows you to enhance your text in ways that may not normally be available through the software. For example, many word processing programs do not offer italics. By inserting a command in your document, however, you can use italics anywhere you like. The
4-6 Using Software and Graphics
commands that your printer recognizes are listed in the Command
Summary in Chapter 8 and on the Quick Reference card at the back of this manual.
Using the Command Summary
The commands listed in the
Command Summary in Chapter 8 consist of various combinations of ASCII codes. You can use either the ASCII characters or their decimal or hexadecimal equivalents. For example, the command to turn on subscript is ESC
S1 in ASCII characters. The decimal format for this command is 27 83 01, and the hexadecimal format is 1B 53 01.
In the Command Summary, commands are grouped by the printer functions they control, such as character pitch, print enhancement, and graphics. You can also look up commands in the list of software commands in numerical order at the beginning of the Command
Summary. This list gives you page number references for the commands.
Some commands include a variable, such as the letter n. For example, the command for selecting or cancelling double-high mode is ESC w n.
When n = 1, double-high mode is turned on, and when n = 0, it is turned off. In the Command Summary, variables are printed in italics to distinguish them from ASCII characters.
Sending printer commands from within your software program
How you format commands depends on the software program you are using. Some software programs accept only the decimal format, while others require certain punctuation. Some programs don’t let you insert printer commands at all.
If your software does allow you to send commands to the printer, use the
Command Summary to find the command you want to send. Your software manual should explain exactly what format and punctuation are required.
Using Software and Graphics
4-7
Dot Graphics
The dot graphics mode allows your FX printer to produce pictures, graphs, charts, or almost any other pictorial material you can devise.
Because many commercial software programs use graphics, you may be able to print pictures and graphs like the ones on this and the following page simply by giving your software a few instructions.
4-8 Using Software and Graphics
The quickest and easiest way to print graphics on your printer is to use a commercial graphics program. With such programs you usually create an image on your monitor and then give a command to send the image to the printer.
If you use commercial software that produces graphics, all you need to know about dot graphics is how to use the software. If, hand, you wish to do your own understand how the FX prints graphics, read on the other programming or merely wish to on.
The print head
To understand dot graphics you need to know a little about how the FX’s print head works.
The print head has nine pins. As the print head moves across the page, electrical impulses cause the inked ribbon and presses it against the paper to produce a small dot.
As the the pins to fire. Each time a pin fires, it strikes head moves across the paper, the pins fire time after time in different patterns to produce letters, numbers, or symbols.
Using Software and Graphics 4-9
The print head is able to print graphics in addition to text because graphic images are formed on the FX about the same way that pictures in newspapers and magazines are printed. If you look closely at a newspaper photograph, you can see that it is made up of many small dots. The FX this section.
also forms its images with patterns of dots. The images printed by the FX can be as finely detailed as the ones at the beginning of
In its main graphics mode the FX prints one column of dots for each code it receives, and it uses only the top eight of the nine pins. Therefore, your graphics program must send codes for dot patterns, one number for each column in a line. For each of those columns the print head prints the pattern of dots you have specified.
To print figures taller than eight dots, the print head makes more than one pass. The printer prints one line, then advances the paper and prints another, just as it does with text.
To keep the print head from leaving gaps between the graphics lines as it does between the text lines, the line spacing must be changed to eliminate the space between lines. With a change in line spacing, the FX can print finely detailed graphic images made up of adjacent lines, each no more than 8/72-inch tall.
Each pass of the print head prints one piece of the total pattern, which can be as tall or short and as wide or narrow as you desire. You don’t have to fill the whole page or even an entire line with your graphics figures. In fact, you can use as little or as much space as you like for a figure and put it anywhere on the page.
Pin labels
The graphics mode requires a method to tell the printer which pins to fire in each column. Since there are 256 possible combinations of eight pins, you need a numbering system that allows you to use a single number to specify which of the
256 possible patterns you want. By labelling each pin with its own number, you can use a numbering system that allows you to specify exactly which pins should be fired.
To fire any one pin, you send its number, according to the numbering system shown in the figure on the next page. To fire more than one pin at
4-10 Using Software and Graphics
the same time, add up the numbers of the pins and send the sum to the printer. Therefore, with these labels for the pins, you fire the top pin by sending 128. To fire the bottom pin, you send 1. If you want to fire only the top and bottom pins, you simply add
128 and 1, and send
129.
By adding the appropriate label numbers together, you can fire any combination of pins. The figure below shows three examples of how to calculate the number that fires a particular pattern of pins.
128

With this numbering system, any combination of the eight pins adds up to a decimal number between 0 and
255, and no numbers are duplicated.
Before you can put these numbers in a graphics program, however, you need to know the format for graphics commands.
Graphics commands
Graphics commands are quite different from most other commands. For most of the other modes, such as emphasized and double-wide, one command turns the mode on and another turns it off. For graphics, the command is more complicated because the command that turns on a graphics mode also specifies how many columns of graphics will be printed. After the printer receives this command, it interprets the next numbers as pin patterns and prints them on the paper.
The graphics command format
There are several different graphics commands giving different horizontal dot densities and printing speeds. Because the format is almost the same for all the commands, however, the example here keeps things simple by using only the single-density graphics command, density graphics, there are
60
ESC K. In singledots per inch horizontally.
Using Software and Graphics 4-11
The command to enter single-density graphics mode is ESC K n1 n2. In
BASIC the command is given in this format:
LPRINT CHR$(27);1tKf';CHR$(nZ);CHR$( n2);
In this command, ESC K selects single-density graphics, and n1 and n2 specify the number of columns to reserve for graphics.
Column reservation numbers
The graphics command requires more than one number to specify how many columns to reserve because although one line can use thousands of columns, the FX does not use numbers larger than 255 (decimal).
Therefore, the graphics mode command uses two numbers for reserving columns.
To figure n1 and n2, divide the total number of columns by 256. The result is n2; the remainder iS n1. Since the command is set up for two numbers, you must supply two numbers even if you need columns you are reserving and make n2 a zero.
only one.
When you need fewer than 256 columns, just make n1 the number of
For example, if you wish to send 1632 columns of graphics data, n1 should be 96 and n2 should be 6 because 1632 = 96 + (6 X 256).
Graphics data
After receiving a graphics command such as ESC K n1 n2, the printer prints the number of codes specified by n1 and n2 as graphics data, no matter what codes they are. This means that you must be sure to supply exactly the right amount of graphics data. If you supply too little, the printer stops and waits for more data and seems to be locked. The next data sent will then be printed as graphics, even if it is really text. On the other hand, if you supply too much graphics data, the excess will be printed as regular text.
Graphics programming
Here is an example that shows how a graphics command, column reservation numbers, and data can be used to print a single line of graphics. The example is a BASIC program. You can, of course, use another programming language. The principles are the same.
4-12
Using Software and Graphics
The first line of the program specifies single-density graphics for 40 columns:
100 LPRINT CHR$(27);"K";CHR$(@);CHR$(@;
The second line is the data that is printed as pin patterns. It uses the number
74 to produce one of the patterns shown above. The FOR-NEXT loop sends 40 columns of data.
Here is the second line of data:
2@g FOR X=1 TO
48:
LPRINT CHR$(7L,);: NEXT X
That is the whole program. In BASIC, semicolons at the ends of the lines are very important; they prevent the computer from sending other codes after the ones you specify. In other languages you may have to use a special command to send a single code at a time. Run the program to see the result below. Although it is not as interesting as the examples at the beginning of this chapter, it shows exactly how the graphics mode works.
WIDTH statements
Some software programs (including most versions of BASIC) automatically insert carriage return and line feed codes after every 80 or
130 characters. This is usually no problem with text, but can spoil your graphics. Two extra columns of graphics are printed in the middle of the ones you send, and two data numbers are left over and printed as text.
In some versions of BASIC you can prevent unwanted control codes in graphics by putting a WIDTH statement at the beginning of all graphics programs. The format in many forms of BASIC is either WIDTH
“LPT1:“, 255 or WIDTH LPRINT 255. Check your software manual for the proper format.
Printing taller patterns
The next example shows how several lines of graphics can be formed into a figure taller than eight dots. It uses programming techniques for producing textured or repetitive patterns.
Using Software and Graphics 4-13
The program is listed below. The lines inside each pair of FOR and
NEXT statements have been indented so that you can see how the program works; the spaces are not needed for the program to run.
1Qp WIDTH "LPTl:", 255 ll@ LPRINT CHR$(27);"A";CHR$(8);
12@ FOR R = 1 TO 6
138 LPRINT CHR$(27);"K";CHR$(l@);CHR$(@);
14a FOR X = 1 to 58
158 LPRINT CHR$(17@);CHR$(85);
16P
NEXT X: LPRINT
17@ NEXT R lSp! LPRINT CHR$(27);"@"
If you run the program, you will see how it combines six print lines into a pattern.
There are five basic steps that the program goes through to produce this kind of pattern.
1.
The computer is prevented from adding any extra characters by the
WIDTH statement (line
100).
2. The line spacing is changed to 8/72 of an inch-the height of the dot patterns used in the program (line
110).
3. The program goes through the graphics commands the required number of times (lines 120 and
170).
4.
A new graphics command is used for each line printed (lines 130-160).
This part of the program is similar to the last example, but two columns are printed each time through the loop making a total of
100.
4-14 Using Software and Graphics
5. The last important thing to do is to reset the printer to its default settings, including the normal line spacing (line
180).
Notice that the graphics command (ESC K) can be in effect for only one print line. To print more than one line of graphics, the graphics command must be issued before each line.
Density varieties
Although all the examples so far in this section have been in the singledensity graphics mode, there are seven other eight-pin densities and two that use all nine pins.
Nine-pin graphics is not necessary for most uses, but you can find the command (ESC *) in the Command Summary in Chapter 8. The four most common eight-pin modes are ESC K, ESC L, ESC Y, and ESC Z.
There is also a general purpose command for any of the eight-pin graphics modes: ESC *. This command is used in the same way as the individual commands, except that before n1 and n2 you must send the code for the graphics mode required.
The different graphics modes are summarized in the following table:

Modes 4, 5, 6, and 7 are special modes that alter the horizontal density to give the proportions of a computer monitor (the CRT modes) or to match the vertical density so as to give round circles
(the plotter mode).
In two modes, high-speed double-density and quadruple-density, the print head cannot print two consecutive dots with the same pin, so it
Using Software and Graphics 4-15
prints dots in only half the possible dot positions in any one row. The higher density means that the resolution of the pattern is better than in single-density mode. When you design patterns in these two modes, however, you must make sure that no dots overlap.
Reassigning a graphics mode
Another graphics command lets you assign a different eight-pin graphics mode to one of the specific eight-pin graphics commands. You can use this command with graphics software programs to quickly change the density and proportions of your printouts. Changing the graphics option changes the width without changing the height.
The command for reassigning a graphics mode is ESC ? c m. In this command, c is a letter designating one of the four alternate graphics codes (K, L, Y, or Z) and m is the mode number of the new mode, as listed in the table on page 4-15.
For example, to change the ESC K command to select the CRT I screen graphics mode, the command in BASIC is’ the following:
LPRINT CHR$(27);"?K";CHR$(4);
A little experimentation should tell you whether the reassigning command can improve your graphics printouts.
Designing your own graphics
This section takes you through the development of a graphics program.
The example is not especially complicated, but it does include the same steps you would use for a more complex figure.
You should plan your figure with dots on graph paper, but before beginning to place the dots, you must decide which graphics density you want. The figure on the next page shows the differences between three common modes.

In this figure you can see the main rules for graphic design in the three densities: l
In single-density no dots can be placed on vertical lines.

In high-speed double-density, dots can be placed on vertical lines, but no dots can overlap.
l
In double-density, dots can be placed on vertical lines, and they can overlap.
Now look at the high-speed double-density design below. It should point you in the right direction for your own work.

After plotting the dots on a grid, you calculate the numbers for each pin pattern by dividing the design grid into separate print lines. For the arrow design, the grid was divided into two lines, results for the seven dots high.

The numbers for the second line were calculated in the same way. Once the numbers for the pin patterns are calculated, they are put in the program in DATA statements, separated by commas.
The program works in a similar way to the example before. This time it selects 7/72-inch line spacing because only seven pins are used. Because the data is not repetitive, each column of graphics data is read from the
DATA statements and sent to the printer. The design is wide. Therefore both lines 130 and 140

User-Defined Characters
The FX has several hundred different characters stored in its ROM (Read
Only Memory). Although this number includes draft, italic, international, Epson Extended Graphics, and NLQ (near letter quality) characters, sometimes you may want to have a few more. For those occasions when you need a special character or a few letters in a different typeface, the FX allows you to create your own characters and print them just as if they were ordinary letters.
You can make the task of defining characters easier by using a commercial software program that either assists you in creating
Using Software and Graphics 4-19
characters or simply supplies you with sets of characters already created.
Also, some popular commercial software programs take advantage of the printer’s user-defined character function to enhance printouts. These characters are sometimes called download characters.
Defining your own characters
The printout below displays a few such characters to give you an idea of what can be done, but remember that since these characters are truly user-defined, you can create whatever you need or want.
DIP switch 1-1 must be off before you can create a user-defined character. The procedure for designing a character is a simple three-step process:
1. Plan your character.
2. Run a program to test your work and calculate the required DATA numbers.
3. Run another program to put the character in your printer’s memory for use whenever you need it.
Once you define a character, you can print it in either draft or NLQ. If you print it in NLQ, the printer adds dots to make the character more fully formed.
After you have created your own characters with these programs, certain keys that you seldom use generate the user-defined characters. For example, you can press the ( key to print !$ .
You can create any type of character. The only restriction is that the characters you define must follow the same rules that govern the rest of the characters printed by the FX. They must fit into an 11 x 9 matrix, no dot can overlap another (in draft mode), and either the top or the bottom row must be empty.

Because the last two columns are reserved for the space between characters, they are not included in the grid. And since most characters do not use the bottom two rows, there is a heavy line to indicate the usual lower limit for an FX character.
When you place your dots on this grid, remember that dots cannot go on horizontal lines, but they can go on vertical lines. If they overlap other dots, they will not be printed in draft, only in NLQ. characters, draw the dots as large as
As you design your the circles you see in the example below. (The printer prints dots, but it is best to use circles when planning your characters.)

When printed by your own program, these two lines provide you with a key to the characters your FX can now print. When you press the key for one of the characters in the top row, the printer prints the corresponding character in the bottom row. In the example above, if you type < your
FX prints B (although your screen continues to show the character < ).
If you have designed a few characters and want to use them with your word processing program, for example, just run the second definition program before you start using your word processing program. Then use the two-line printout as your guide to tell you which keys to press for your new characters.

Data Dump Mode
The printer has a special feature to make it easy for experienced users to find the cause of communication problems between the printer and application programs. In data dump mode, an exact printout of the codes reaching the printer is produced.
1. To enter the data dump mode, hold down the FORM FEED and LINE
FEED buttons at the same time while you turn on the printer.
2. Next, run either an application program or one you have written in any programming language. Your printer prints all the codes sent to the printer in hexadecimal format as shown below:

3. To turn off the data dump mode, press the ON LINE button to take the printer off line, and then turn off the printer. (The data dump mode can also be cancelled by sending an INIT signal from the computer.)
Look at the data dump shown in Step 2. By comparing the characters printed in the right column with the printout of the hexadecimal codes, you can check what codes are being sent to the printer. If characters are printable, they appear as their true ASCII characters. Nonprintable codes, such as control codes, are represented by dots.
As an example of how to interpret a data dump printout, look at the first three hex codes on the second line of the printout sample (20 20 54). Each hex 20 represents a space, while hex 54 represents the letter T. Check the second line of the right column and you will find the letter T preceded by two spaces.

Recommended paper
Paper: For best results, use typewriter-quality paper. If you use paper with a glossy or textured surface, you should test it before regular use. The cut sheet feeder can hold up to 150 sheets of paper. Do not use multiple-part forms or labels.
Envelopes: You can print on air mail, plain, or bond envelopes. The cut sheet feeder can hold up to 25 plain or bond envelopes, or
30 air mail envelopes. Before printing on envelopes, you need to set the paper thickness lever. See the section on printing on special paper in Chapter 2.

Envelope loading
Envelopes are loaded in much the same way as regular paper. To load envelopes, you need to do the following:
1. Set the paper thickness lever to match the thickness of your envelopes. (For specific information on paper thickness settings, see the section on printing with special paper in Chapter 2.)
2. Follow steps 1 through 5 of the previous section on paper loading to load envelopes. You can load up to 25 plain or bond envelopes, or 30 air mail envelopes.
3. Push down on the two front levers until they lock into position.
Using the cut sheet feeder
After loading paper into the cut sheet feeder, make sure the ON LINE light is on. Once the printer is in the sheet feeder mode, a new sheet of paper loads automatically whenever a printable character or line feed command is sent to the printer.
When the cut sheet feeder runs out of paper, it stops paper feeding and the PAPER OUT light comes on. To start printing again, load more paper

sand then press the ON LINE button. The printer starts printing from the point at which it was stopped.
If you turn your printer off during the time the printer detects a paper out or paper jam condition, any data remaining in the printer’s buffer is discarded.
Software operation
This command causes the printer to eject the sheet in the printer without loading the next sheet:
FF form feed
The sheet in the printer is automatically ejected and the next sheet is loaded if the paper reaches the bottom of the print area when any of the following line feed commands is used:
LF line feed; advances the paper by one line
VT
ESC J vertical tab; advances the paper to the next vertical tab position performs line feed in units of 1/216 of an inch.
Setting up your software
When you switch between continuous paper and cut sheet feeder paper you usually need to change the settings of your software program.
Because of the physical requirements of feeding a single sheet of paper, sheet feeders create a top and bottom margin on each sheet. To work properly, your software program needs to know how many printable lines are available on the page.
Paper comes in many different sizes and it is sometimes difficult to know exactly how many printable lines per page you have. When you perform a self test in sheet feeder mode, the printer automatically counts and prints the number of lines that are available on any size of paper. This is the number of lines you should use as the page length in your software setup. See the following section on the self test in cut sheet feeder mode for more details.
Using Printer Options 7-9
In addition to the number of printable lines, which your software may refer to as page length or form length, you may need to set the top margin, the bottom margin, and the actual number of lines to be printed on the page. The cut sheet feeder normally creates a two-line unprintable top margin. Therefore, if you want a total top margin of six lines (one inch), set the top margin in your software to four lines. The sheet feeder usually creates an unprintable bottom margin of about three lines, so to create a total bottom margin of six lines, set the bottom margin in your software to three lines. With a total page length of 61 printable lines, for example, the number of printed lines per page would be 54 (9 inches).
Some software designed only for printing on continuous forms does not use the form feed command recommended for sheet feeder operation.
The software may not have a sheet feeder setup mode or allow for margin settings, and may only use line feeds to advance to the next form.
Your sheet feeder can still work with most of these applications. Simply insert the paper you will be using into the sheet feeder, use the self test to print out the number of printable lines, and then use that number of lines as the page length setting in your software. If you change paper sizes, repeat this process. Your sheet feeder will work as if it were feeding a continuous form. If your software does not allow you to set the page length, consult your software manufacturer.
The following is a typical example of a software setup required for proper operation of your cut sheet feeder. Not all software is set up the same, so a bit of experimentation may be required before you find the best equivalent settings to use. To maintain 54 printed lines per page:

All of the functions from the control panel are available in cut sheet feeder mode. You can use micro-adjustment to change the loading position immediately after loading a sheet using the single sheet insertion method described on page 7-14. Micro-adjustment sets a new sheet loading position for as long as the power remains on. If the power is turned off, the loading position returns to the factory setting. Changing the loading position with micro-adjustment affects the number of lines per page. You may need to change your software margin settings again for this new page length. See the section on micro-adjustment in
Chapter 2.
Testing the printer in the cut sheet feeder mode
The printer’s built-in self test in the cut sheet feeder mode is slightly different from that of the original self test. To test the printer in cut sheet feeder mode, load the paper you will be using into the paper bin. Hold down the LINE FEED or FORM FEED button and turn the power switch on as described in Chapter 1.
When you perform the cut sheet feeder self test, the printer counts the number of lines on the page and prints out this number at the bottom of the first page as shown in the following figure. The number of lines counted by the printer becomes the new default page length setting for the cut sheet feeder mode. You can override this setting, however, using software commands.
The self test is especially useful when you want to change the page length settings for your application program, because it gives you a quick count of the number of lines on the page.
Using Printer Options 7-11
Below is a portion of the first page of a self test in cut sheet feeder mode.
The remainder of the self test is similar to the original self test described in Chapter 1.
WARNING: Never perform the self test on envelopes.
Switching from the cut sheet feeder to continuous paper
The FX allows you to switch between cut sheet feeder paper and continuous paper easily without having to remove either the feeder or the continuous paper supply. To switch between these two paper feeding methods, follow the steps below.
1.
Make sure the continuous paper is already loaded and in a standby position, as explained in the section on switching between single sheets and continuous paper in Chapter 2.
2.
Install the cut sheet feeder as described in this section, making sure that DIP switch 2-2 is set to on, and that the paper release lever is pushed all the way back to the single sheet position.
7-12
3.
To switch from cut sheet feeder operation to continuous paper, pull the paper release lever all the way forward to the continuous paper position. You do not need to change the DIP switch setting.
4.
Raise the paper path guide on the cut sheet feeder until it clicks open, as shown below. This guide directs the flow of continuous paper out of the
front of the printer.
5.
With the paper release lever foward, the control panel functions normally. This allows you to use micro-adjustment to adjust the loading position of your paper.
6.
To switch back to the cut sheet feeder, push the LOAD/EJECT button until the continuous paper feeds backward out of the paper path and into a standby position. Push the paper release lever back to put the printer into the sheet feeder mode, and then close the paper path guide.
Using Printer Options 7-13
Single sheet insertion
Your cut sheet feeder also has a single sheet loading feature. This feature allows you to switch to a different type of paper (such as letterhead) without replacing the supply of paper that is loaded in your cut sheet feeder. Single sheet insertion is especially useful because it allows you to use micro-adjustment to change your cut sheet feeder loading position.
1.
Press the ON LINE button to take the printer off line.
2.
Align the single sheet to be fed with the marking on the left paper guide, and then slide the sheet into the printer path until you feel resistance.
3.
Press the LOAD/EJECT button to load the sheet.
Note: If you want to use single sheet insertion for two or more consecutive pages, pull the cut sheet feeder’s paper set levers forward; otherwise, the next sheet is loaded from paper stored in the cut sheet feeder bin.
4.
Press the ON LINE button to put the printer on line. Now you can use micro-adjustment to change the loading position for your cut sheet feeder. See the section on micro-adjustment in Chapter 2.
7-14 Using Printer Options
The Pull Tractor
The optional pull tractor (#7311 for the FX-850 and #7312 for the
FX-1050) provides optimum continuous paper handling. The pull tractor is especially useful with continuous multi-part forms and labels. For best results, use the pull tractor along with the built-in push tractor, as described in this section.
After making sure that you have both parts of the pull tractor option as shown below, remove the packing material and save it in case you need to ship the unit later.
Caution: The short tear-off function cannot be used with the pull tractor. Before you start printing with the pull tractor, make sure that
DIP switch 1-5 is set to on. (Short tear-off is turned off only when the
DIP switch is set to on. See the section on setting DIP switches in
Chapter 3.)
Installation and use
After making sure that the printer is turned off, install and use the pull tractor as follows:
1. Remove the printer cover and the paper guide and install the paper rest if you haven’t already. (See Chapter 2.)
Using Printer Options 7-15
2.
Remove the paper tension unit by pressing open the release levers and lifting up the front of the unit at the same time.

6.
Tilt the tractor unit toward you until the front latches click in place over the front mounting pins of the printer.
Now load paper as described in the section on loading continuous paper in Chapter 2. However, position the left sprocket unit about
1/4 of an inch from the left before locking it in place.
After the paper is loaded in the push tractor, make sure the printer is off line and then press the FORM FEED button. This advances the paper one page so you can fit the paper onto the pull tractor.
Caution: Never use the platen knob to feed the paper while the printer is turned on. If you need to adjust the loading position, use the microadjustment function described in Chapter 2.
7. Open the sprocket covers, and release the sprocket lock levers.
Using Printer Options 7-17
8. Move the sprocket units to match the width of the paper and adjust the paper supports so they are evenly placed between the sprocket units. (There is only one paper support on the FX-850 pull tractor.)
9. Fit the holes of the paper over the tractor pins of the sprocket units, adjusting the position of the sprocket units as necessary.
7-18 Using Printer Options
10. If the paper does not fit exactly onto the tractor pins, press in on the pull tractor feed knob and turn it in the desired direction.
11. Close the sprocket covers.
12. Make sure that the paper is not crooked or wrinkled and then lock the sprocket units in place.
Using Printer Options 7-19
13.
Slide the rollers on the paper bail so they are evenly distributed across the width of your paper. Also, make sure that the right and left rollers are at both edges of your paper.
14.
Re-install the paper guide and then slide the edge guides together so they meet at about the middle of the paper’s width.
15.
Install the pull tractor cover.
7-20
Using Printer Options
16.
Press the ON LINE button to put the printer on line. Now you are ready to begin printing.
When you are finished printing
The short tear-off function cannot be used with the pull tractor. If you want to tear off the last printed page at its perforation, press the ON LINE button to take the printer off line and press the FORM FEED button to feed the paper forward an additional page before tearing off the paper.
Using the pull tractor alone
If you wish, you can use the pull tractor without using the push tractor.
To do this, feed the paper from the rear, above the metal guide, and then load it. Be sure to pull the paper release lever forward to the continuous paper position after you load the paper.
Removing the pull tractor
After turning off the printer and removing the pull tractor cover, remove the pull tractor as follows:
1.
Pressing the tabs on the pull tractor, tilt it back and lift it off the printer.
Using Printer Options 7-21
2. Replace the paper tension unit as shown below.
3. Now you are ready to use either single sheets or the push tractor.
Interface Boards
There are a number of optional interfaces that can be used to supplement the capabilities of your printer’s built-in parallel interface.
Choosing an interface
Optional interfaces can be divided into three main categories: l l
IEEE-488 interfaces offer standardized connections, trouble-free operation, and the ability to connect computers, printers, and other devices on the same line so that they can share data freely.
Buffered parallel interfaces give the printer more memory and free up the computer for other tasks when printing large amounts of text or graphics. With a buffered parallel interface, you can increase the printer’s data buffering capacity to 32 Kbytes (about 10 pages).
Parallel interfaces also offer the advantage of trouble-free operation combined with standardized connectors.
7-22 Using Printer Options
l
Serial interfaces are necessary if your computer is not equipped with a parallel interface or if you need an interface that conforms to the
Current Loop standard instead of the RS-232C. In addition, all available serial interface boards provide user-selectable baud rates and data word structures. These interfaces also offer some combination of the following features: X-on/X-off data communication protocol, loopback self-test modes, and data buffers that increase the printer’s buffering capacity to either 32 Kbytes or
128
Kbytes.
If you are still unsure whether you need an optional interface, or would like to know more about interfaces, contact your Epson dealer.

Removing the upper case
Before installing an optional interface board, you must remove the upper case. This is easy to do; the only tool you need is a Phillips screwdriver.
Follow the instructions below:
1. Turn off both the printer and the computer, unplug the printer from the electrical outlet, and disconnect the parallel cable from the printer and computer.
Using Printer Options 7-23
WARNING: High voltage is present inside the printer when the power is on. Do not attempt to remove the upper case unless the printer is turned off and the power cord is unplugged. Also, do not touch contacts on the printer’s circuit board because many of the components can be destroyed by static electricity built up in your body.
2.
Remove the printer cover, paper guide, ribbon cartridge, and any installed options.
3. Remove the platen knob and push the paper release lever back to the single sheet position.
4. Remove the screw located inside the front center of the upper case.

Installing the board
There are two basic interface board designs. These boards differ with respect to how the frame ground (FG) wire is attached. This slight difference changes the way the boards are installed in the printer, but does not affect the operation of the interface in any way. Look at the following illustration to see which type of interface board you have and then follow the installation procedure for that type of board.
FG wire not attached
See below

Command Summary
This chapter lists and describes all the commands, both Epson (ESC/P) mode and IBM emulation mode, available on the FX.
The first part of this appendix lists all commands in numerical order and gives the page number where each is fully described. If you know which command you are looking for, consult the numerical list to find the page number where it is described.
The Quick Reference card at the end of the book also contains a list of the commands divided by topic, with page number references that direct you to full explanations of the commands. The numerical list and the
Quick Reference card also show the differences between the Epson mode and the IBM emulation mode.
The second part of this appendix lists and describes Epson mode commands and IBM emulation mode commands separately; the commands are divided into the following subjects:
Printer Operation
Data Control
Vertical Motion
Horizontal Motion
Overall Printing Style
Size
Print Enhancement
Word Processing
Character Sets
User-Defined Characters
Graphics
Each command has a format section and a comment section. The format section gives the ASCII, decimal, and hexadecimal values for the command; the comment section describes the effect of gives any additional information necessary for using it.

All three formats are equivalent, and it should be easy to pick most suited to your purpose.
the one
Note: Some application programs can use control key sequences. See the Control Key chart on page 8-3 for information on using these.
Command Summary 8-1
The simplest type of command consists of a single character to be sent to the printer. For instance, to print in condensed mode the code format is:
ASCII code:
SI
Decimal:
15
Hexadecimal: 0F
This code can be sent from a program by sending the code
15 directly.
More complex commands consist of two or more character codes. For example, to print in double-wide mode the code format is the following:
ASCII code:
Decimal:
ESC W n
Hexadecimal:
27 87
1B 57 n n
In this case n can be either print from BASIC:
1 or 0, to begin or end double-wide printing.
You can use either of the following commands to turn ON double-wide
LPRINT
CHR$(27);CHR!$(87);CHR!§(l)
LPRINT CHR!§(27);“W”; CHR!$( 1)
For the following commands that use only the ASCII codes
0 or
1 for the variable, either
1 and
0 or the ASCII characters
1 and
0 can be used:
ESC s, ESC U, ESC x, ESC p, ESC W, ESC S, ESC-, ESC w, and
ESC %
For example, in BASIC you can turn on double-high with either of these statements:
LPRINT CHR$(27); “w”; CHR$( 1)
LPRINT CHR!$(27);“w”;“l”
8-2 Command Summary
Control key chart
Some application programs can use control key codes for decimal values
0 through
27.
The table below gives you the proper values. The Control
Key column indicates that you press the control key at the same time you press the key for the letter or symbol in that column. For example, you press the control key and A at the same time to send the value
1.
Note: Many programs use the control keys for other purposes. Also, some programs do not use all these keys.

The column heading “Direction” refers to the direction of signal flow as viewed from the printer.
0 “Return” denotes the twisted-pair return, to be connected at signal ground level. For the interface wiring, be sure to use a twisted-pair cable for each signal and to complete the connection on the return side. These cables should be shielded and connected to the chassis of the host computer and the printer.
All interface conditions are based on TTL level. Both the rise and the fall times of each signal must be less than 0.2 microseconds.
Data transfer must be carried out by observing the ACKNLG or
BUSY signal. Data transfer to this printer can be carried out only after receipt of the ACKNLG signal or when the level of the BUSY signal is LOW.
Printing enabled/disabled signals and control conditions
The following table shows the relationship between printing being enabled or disabled, the on line/off line status, and the receipt of the data on/off control characters, DC1 or DC3.

Proportional Width Table
This table lists the widths of your printer’s proportional characters. The values given are in 120ths of an inch. (For example, a value of 12 is
12/120ths of an inch.) You may need to enter these widths into a special table for your word processing program so it can calculate the number of proportional characters that will fit on a line.
The characters with no code indicated are international characters or graphics. See the table in the section on international character sets in
Chapter 3 for the relevant codes for the international characters. Also, see the descriptions of the ESC R and ESC t commands in the Command
Summary for information on how to use these characters.
The following width table shows each code (hexadecimal), its character, and its width. If there are two numbers in the width column, the second one is for the italic character.

Note that these definitions apply specifically to printers. If a word is italicized, see that topic for more information.
application program
A program that helps you carry out a particular task, such processing or financial planning.
as word
ASCII
American Standard Code for Information Interchange. A standardized coding system for assigning numerical codes to letters and symbols.
automatic line feed
When this feature is turned on using a DIP switch, each carriage return code (CR) is automatically accompanied by a line feed (LF) code.
baud rate
A measure of the speed of data transmission. Usually equivalent to bits per second.
bidirectional printing
Printing in which the print head goes from left to right only on every other line. On the other lines, it goes from right to left. This increases the speed of printing because the head prints in both directions.
binary
See number systems.
bit
A binary digit (0 or l), which is the smallest unit of information used by a printer or computer. See also number systems. buffer
See memory.
byte
A unit of information consisting of eight bits.
Glossary GL-1
carriage return
The control code that returns the print position to the left margin. When issued together with a line feed, the print position moves to the left margin of the next line. In bidirectional printing, the print head may not actually move to the left margin.
characters per inch (cpi)
A measure of the size of text characters, often referred to as pitch. 10 cpi
(also called pica) is often the standard or default setting.
character set
A collection of letters, numbers, and symbols that provides you with the characters used in a particular language.
condensed
Printing in which each character is approximately 60% of the width of standard characters. Useful for fitting wide tables or spreadsheets onto the paper.
continuous paper
Paper that has sprocket-feed holes on each side, is perforated between pages, and comes in a folded stack. Also called fanfold paper.
control code
Besides the codes for printable characters, the ASCII standard also includes 33 other codes called control codes. These control codes perform such functions as sounding the beeper and performing a carriage return or line feed.
cut sheet feeder (CSF)
An optional, detachable device that automatically feeds single sheets of paper into the printer.
data dump
A troubleshooting feature. When the printer is in data dump mode, each code that it receives is printed in hexadecimal notation as well as the
ASCII codes that stand for the characters. Sometimes called hex dump.
decimal
See number systems.
GL-2 Glossary
default
A value or setting that takes effect when the equipment is turned on, reset, or initialized.
DIP switches
Small switches in a printer that control various printer functions and set the default status of the printer when it is turned on or initialized. DIP stands for Dual In-line Package.
dot graphics
A graphic design formed by patterns of dots.
dot matrix
A method of printing in which each letter or symbol is formed by a pattern (matrix) of individual dots.
double-high printing
Printing in which each character is twice as high as normal.
double-strike printing
A way of producing bolder characters. Each character is printed twice; the second time, the dots are printed slightly below the original dots.
Can only be used in draft mode.
double-wide printing
A print width in which each character is twice as wide as normal characters. (Double-wide was formerly known as expanded.) draft
One of two print qualities available on your printer. Draft uses a minimum number of dots per character for high-speed printing. See also near letter quality. emphasized printing
A way of producing darker characters. Each character is printed twice, with the second slightly to the right of the first.
Epson Extended Graphics
The Epson Extended Graphics character table contains international accented characters, Greek characters, and character graphics for printing lines, comers, and shaded areas.
Glossary GL-3
ESC (escape)
A special control code used to begin most printer commands.
ESC/P
Abbreviation for Epson Standard Code for Printers. The system of commands lets you control your printer using your computer’s software.
It is standard for all Epson printers and supported by most applications software for personal computers.
font
A style of type designated by a family name.
form
In printer terminology, a form is normally the equivalent of a page.
form feed
A control code and a control panel button that advances the paper to the top of the next form.
hexadecimal (hex)
See number systems.
initialize
To establish the initial default status of the printer by turning the printer on or sending an INIT signal.
interface
The connection between the computer and the printer. A parallel interface transmits data one character or code at a time, and a serial interface transmits data one bit at a time.
italic
A typestyle in which the characters slant. This sentence is italicized. near letter quality (NLQ)
One of two print qualities available on your printer. Near letter quality reduces the print speed and increases the number of dots per character to increase the print quality. See also draft. line feed
A control code and a control panel button that advances the paper one line space.
GL-4 Glossary
memory
The printer, like a computer, has a memory. When you print a file from a computer, the contents of the file are transferred quickly from the computer’s memory to the printer’s memory. The printer then prints information from its own memory at a much slower rate. This way of printing frees the computer to do other work while the printer is still working. The printer memory is sometimes called the buffer.
micro-adjustment
A feature that adjusts the paper loading and tear-off positions.
number systems
Three number systems are commonly used with printers: decimal is base 10 and uses the digits 0, 1, 2,
3, 4, 5, 6, 7, 8, and
9.
(This is the most familiar system.) hexadecimal (hex) is base
16 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8,
9, A, B, C, D, E, and hex number.
F. This is frequently used by programmers. Any decimal number between 0 and 255 can be expressed by a two-digit binary is base 2 and uses only the digits 0 and
1.
All information in computer systems is handled in binary form to represent electrical signals that are on or off. A binary digit is often called a bit; any decimal number between 0 and
255 can be expressed by an eight-bit binary number.
on line
When the printer is on line, it can communicate with the computer connected to it, paper-out sensor
A small switch behind the platen that sends a signal when it is not in contact with paper, causing the PAPER OUT light to go on.
paper tension unit
The part of the printer that fits on top of the platen to ensure proper paper feed tension.
parallel interface
See interface.
Glossary GL-5
Parity is a method for a computer and printer to check the reliability of data transmission.
pitch
Indicates the number of characters per inch (cpi). The standard is 10 pitch.
platen
The black roller that provides a backing for the printing.
print quality
Your printer has two types of print quality: draft and near letter quality
(NLQ). Draft is for high-speed, draft-quality jobs; NLQ is for final, polished documents.
proportional printing
Printing in which the width of character. For example, an the character varies from character to uppercase W receives much more space than a lowercase i. The result looks more like a typeset book than a typewritten draft.
push tractor
The built-in device that feeds continuous paper through the printer.
Random Access Memory. The portion of the printer’s lost when the printer is turned off.
memory used as a buffer and for storing user-defined characters. All data stored in RAM is reset
To return a printer to its defaults, by or by turning the printer off and on.
either a command, an INIT signal, self test
A method of checking the operation of the printer. When the self test is run, the printer prints out its current DIP switch settings and the characters that are stored in its ROM.
serial interface
See interface.
GL-6 Glossary
top of form position
The position on the paper that the printer recognizes as the first printable line. For single sheets, this is the position to which the paper is automatically loaded. For continuous paper, this position can set to the current paper position by turning the printer off and on.
user-defined characters
Characters that are defined and stored in the printer by the user. Also known as download characters.
short tear-off
A feature that automatically feeds the perforation of continuous paper to the tear-off position and then feeds the paper back to the loading position. This position can be adjusted by using the micro-adjustment feature.
